'HOISTING-TRUGK.

Specification of Letters Patent.

Patented oct. 12, 1920.

Application led' April 7, 1919. Serial No. 287,952.

To all whom 'it may concern:

Be it known that I, Gnoncn W. JACKSON, citizen of the United States,residing at Belleville, in the county of St. Clair and State ofIllinois, have invented certain new and useful Improvements in Hoisting-Trucks, of which the following is a speciication.

This invention relates to an improved hoisting truck and has as itsprimary object to provide a device of this character particularlyadapted for use about garages, machine shops, or other similar places,for elevating automobile bodies, engines, or other heavy objects.

The invention has as a further object to provide a hoisting truck ofsuch nature that the truck with its load suspended therefrom may bereadily moved from place to place.

And a still further object of the invention is to provide a truck soconstructed that the truck frame may be arranged to extend over theforward end portion of an automobile when the front end of theautomobile may be elevated and suspended from the frame in such positionthat access may be readily had to the engine pan, crank case, and otheradjacent parts of the engine and vehicle.

In the drawings:

Figure 1 is a perspective view showing the manner in which my improvedtruck may be employed for suspending the front end of an automobile inelevated position, the automobile being shown in dotted lines, and thetruck brace employed being removed,

Fig. 2 is an end elevation of the truck,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2 and lookingdownwardly, this view particularly showing the brace member employedwhen moving the truck from place to place with a load suspendedtherefrom,

Fig. 4 is a detail perspective view showing one of the keepers employedfor holding the handles normally elevated in inactive position Fig. 5 isa transverse sectional view particularly showing the hanger of thedevice, and

Fig. 6 is a vertical section through one of the legs shown in Fig. 3viewed from the side of the device.

In carrying the invention into effect I employ a substantially U-shapedarch bar or frame 10. This bar is substantially T- shaped in crosssection and suitably connected to the lower ends of the bar are crossbars 11. These cross bars are also substantially T-shaped in crosssection and are formed at their ends with enlarged bearings 12. A pairof supporting rollers-13 is carried by each bar and these rollers haveswiveled connection with. the bearings 12. Bracing the bar 10 withrespect to the cross bars are brace rods 14. The intermediate portionsof the rods are bolted or otherwise secured to the arch bar and the endportions of the rods thence diverge downwardly at opposite sides of theend `portions of the bar and are bolted or otherwise secured to the endportions ofthe cross bars 11. The arch bar will thus be rigidlysustained with respect to the cross bars. Connected with the lower endportions of the arch bar 10 are handles 15. At their inner ends thesehandles are formed with loops engaged through suitable openings in theweb flange of the arch bar and are thus freely connected therewithwhile, at their outer ends, the handles are equipped with cross pins 16.In connection with the handles I employ keepers for normally sustainingthe handles elevated in inactive position. One of these keepers is shownin detail in Fig. 4 of the drawings. As there illustrated, each of saidkeepers is in the nature of a fork having spaced fork arms 17 andprovided with parallel lugs 18 straddling the web flange of the arch barLto which the lugs are riveted or otherwise secured. Adjacent theirouter ends,the fork arms are formed in their upper edges with oppositelydisposed notches. As shown at the left in Fig. 1, the handles 15 may beswung upwardly between the fork arms 17 of the keepers, when the crosspins 16 of the handles may be engaged in the notches 18, so that thehandles will thus be held in a substantially upright position out of theway. It will also be noted; that when a handle is allowed to fall to theground, as shown at the right in Fig. 1, the cross pin in the free endof the handle may be utilized as an anchor to prevent moving of thetruck as it is necessary only to drive hook members or staples into theground over the cross pin as will be readily understood.

Slidable longitudinally upon the upper horizontal portion of the archbar 10 is a yoke or hanger 19. As shown in detail in Fig. 5, this hangeris shaped to fit the arch bar so that the hanger will thus be heldagainst canting about the axis of the bar. Depending from the lower sideportion oi thehanger is a medially disposed loop or eye 2O andengagedthrough this eye is the hook of a lhoisting block 2l. Associatedwith this block is a hoisting chain 22 which carries a pulley 23.The'block and pulley are conventionally shown and may be of any approvedtype. Thus, aswill be seen, the truck may be readily moved Vfrom placeto place and positioned over diierent objects whe'n, by properlymanipulating the hoisting block and pulley 23, the object which it isdesired to elevate may be readily hoisted to be held suspended upon thearch bar l0. This arch Vbar is preferably of such height that the truckmay be readilyy positioned over the bodies of automobiles, automobileengines, or like objects, so that'such objects may bereadilyelevated andsuspended upon the truck. --In Fig. l of the drawings I have shown themanner in which the truck may be employedfor holding the liront end ofan automobile suspended, the 'automobile being shown indotted lines.Vhen so used, a rope or other suitable ilexible element is connectedwith the front axle of the vehicle. The hook of the. pulley 23 is thenengaged with the intermediate portion of this rope, when by properlyoperating the chain of the hoisting block 21, the front end of theautomobile maybe readily hoisted and held suspended from the arch bar10. Then so raised, a workman can, as willbe readily seen, easily gainaccess to the engine pan, the engine crank case,'or adjacent parts ofthe vehicle. i

' A pair ofthe handles 15 is, as shown in the drawings, preferablyemployedso that the truck Vmay VbeV readily pulled inV either directionwithout the necessity for turning the truck around. In ordei to avoiddis- Vtortion ofthe arch bar Yl() such as might occur when the truck isbeing moved from place to'place with its load suspended therefrom, Iprovide a brace member oi the type shown in Fig. 3 of lthe drawings.This brace member is constructed ofcrossed'brace bars 24 which areintegrally joined at their intersection and are, as showniu detail inFig. 6,- provided at their ends with eyes 25 snugly engaging over theupper end portionsA of thetrunnions of the rollers 13. l'n

this connection it will be observed that the end'portions of the bracebars are deflected to extend vat substantially right angles to the crossbars while the trunnions of the rollers 13 extend up through the crossbars Y to receivethe ends of the brace-bars. -As will b e seen, thebrace member may thus be readily fittedfin position extending betweenthe cross bars ll sothat when it is desired kto move the'truck fromplace to place with a load thereon, this brace member will prevent theexing of the side portions of the arch bar l0 relative to each other andwill serve torigidly'brace said bar. On the other hand, whenever thevbrace member isfound to be in the way, said member may, as shown YinFig. l, be detached.

Having thus described Vthe invention, what is claimed as new is:

l. A hoisting truckvcomprising an arch,

toot members secured to the ends of the arch, rollers having the upperextremities of their ramesswiveled in and projecting above the ends ofsaid foot members, a bracing frame extending between the foot membersand having its corners removably engaged' over the projecting swivels ofthe roller frames,l and va. hoisting mechanism slidably mounted on thetopmember of the arch. Y 'y Y 2. A hoisting truck comprising an archedbar, T shaped in cross section, rolling sup ports attached to the endsVof said bar, a yoke slidably mounted on the top member of the archedbar, said yoke being T-shapedY Y wherebyV canting or" the same upon thebar is prevented, and a hoisting mechanism sus pended from said yoke.
